Thanks for the replys. I understand the older RAT's but even then did it not just ditch the AC/DC SHED ESS when the RAT stalled ?
Anyway, newer MSN number and the warning is in the fcom along with the point @PENKO points out that with it goes the comms as well.
Point is that the SHED buses do get SHED at certain points but this clearly states the DC ESS BUS is lost at gear extension.
If you check the distribution table for DC ESS BUS there is not one configuration where you lose power to it.
The most demanding situations - 8s when the RAT couples, RAT stalls or on the ground at reducing speed BAT 2 supplies DC ess.
So why is this in there? A hang up from the old days? not even sure that is right - with the RAT stalling on the older MSN numbers I thought you lost the SHED buses only.
If anyone has the FCOM of an old MSN number (smaller RAT) if they could check if it was the AC/DC SHED bus that were lost when the gear was dropped that would be great! A print screen would be good for the older MSN........also if anything is written about the DC EMER CONFIG in the older MSN fcom.
Cheers
